Osteoarthritis of TMJ is a painful deteriorating jaw joint disease. This retrospective cohort study was performed to evaluate the outcome of autologous PRP vs. chitosan injection for TMJ osteoarthritis.
In patients with temporomandibular joint (TMJ)
osteoarthritis, autologous platelet-rich plasma (PRP) injection effectively
mitigates pain with an improved interincisal opening. Nevertheless, it is
associated with greater complications as compared to chitosan injection.
Osteoarthritis of TMJ is a painful deteriorating jaw joint
disease. This retrospective cohort study was performed to evaluate the outcome
of autologous PRP vs. chitosan injection for TMJ osteoarthritis.
The maximum interincisal opening, degree of pain, and TMJ
sounds of 27 patients with TMJ osteoarthritis were noted. These values were
compared prior to treatment and at the 3rd and 6th months following the
treatment. The data of each group (PRP group and Chitosan group) was analyzed
via SPSS 24.0 software. A comparison of imaging
changes in the condylar bone was done before and 6 months following the
treatment.
Patients on PRP
treatment had better results concerning maximum interincisal opening and pain
than the chitosan treatment group. Both groups had relief associated with TMJ
sounds. But, the difference didnot display statistical significance.
PRP treatment displayed improved maximum interincisal
opening and pain in TMJ osteoarthritis as compared to chitosan.
